QUICK VERDICT

Common thresher is about 1.27× longer by these reference values.

Common thresher uses a 7.6 m upper reference, compared with 6 m for Great white shark. Great white shark's weight reference is about 6.7× heavier.

Length bars use upper comparison values and do not show body depth, tail proportion or typical adult size. A long thresher tail, for example, does not equal whale-shark body mass.

WHAT SETS THEM APART

More than a size contest.

Length and weight

Common thresher is represented by reported to 7.6 m / 24.9 ft; Great white shark by about 6 m / 20 ft. Length comparisons can exaggerate body bulk because the tail is exceptionally long. Maximum length and mass are exceptional upper-end figures.

Habitat and diet

Common thresher: Temperate and tropical open waters; schooling fishes and squid. Great white shark: Temperate seas worldwide; fish, rays and marine mammals.

Bite evidence

Common thresher: Its hunting performance cannot be reduced to jaw force. Great white shark: A 3-D finite-element model predicted the bite of a very large individual; it was not measured on a living shark.

Records are not averages

Both species are living, but record-sized individuals are rare. These upper references should not be read as normal adult size.
